Roughly half of the 1,341 cases decided from 2002 to 2013 -- 677 -- involved an attorney donor who gave either before or after the decision. Of these, 138 cases involved attorneys facing disciplinary action from the court. The court also ruled on 120 felony cases, 37 personal injury cases and 31 money judgment cases involving one or more attorney donors.

When looking only at contributions that came in before a case was decided, 331 cases involved an attorney donor.

From 2002 to 2013, there were 338 instances in which a justice ruled in a case involving an attorney donor who gave before a ruling, and only eight in which the justice who received a contribution withdrew.
